Troubleshooting • Re: HM-10 does not talk to raspi 5

Hi,

new trial 1:
'b','c' 1001, 0 Do not bond, 0 do not pair, 0 connection complete time, 'Connect ok as LE client'

I already got 'Connected' with bluetoothctl. I need a tty interface over bluetooth, so 'connected' is not sufficient, right?

new trial 2:
new 'b' disconnects. c 1001,
1 new bond,
2 Pair fixed passkey, Passkey chosen by 0 this local device ,
Fixed 6-digit passkey 123456 (checked and set it with AT commands),

'CONNECTION COMPLETE TIME After connecting, some LE ...... Zero may work... current value=0 (x=cancel to keep) Default value=750,'
Time in ms 0
Pairing complete time1000

Connect OK as LE client
LE A8:E2:C1:46:4D:95 has disconnected
PAIR time out (try larger set_le_wait)

new trial 3:
same with connection complete time 750, pairing complete time 1000
Connect OK as LE client
LE A8:E2:C1:46:4D:95 has disconnected
Pair LE A8:E2:C1:46:4D:95 - not connected as LE server

new trial 4:
this time Pairing and Security 1=yes. ( when does this question pop up?)
Connection timeout 0, pairing timeout 2000
Connect OK as LE client
LE A8:E2:C1:46:4D:95 has disconnected
PAIR time out (try larger set_le_wait)

new trial 5:
this time Pairing and Security 0=no.
Connect OK as LE client

new trial 6:
b, c 1001, connection complete time 750, Connect OK as LE client
It remembers the security settings?

new trial 7:
d 1001, b, c 1001, Connect OK as LE client, still no question for security.

I always connect but cannot pair, same as with bluetoothctl.
Security/passkey is no more questioned after one time Pairing and Security 0=no.
How can I get back?

Hope no tldr
THX
Cheers
